SECTIONAL PLATING DEVICE FOR STRAIGHT-KNITTING MACHINES.

Specification ot Letters Patent.

Patented Feb. 27, 1912.

Application filed December 14, `1910. Serial No. 597,186.

.To all 'whom 'it may concern:

Be it known that I, PAULGUENTIIER, a citizen of the United States,residing at Dover, in the county otl Morris and State of New Jersey,have invented a new and Improved Sectional Plating Devic forStraight-Knitting Machines, ot which the following is a specification.

This invention relates to a straight knitting machine which is soconstructed that selected portions of a stocking or other garment may beplated, while the remaining portions thereof may be formed of but asingle thickness. It has more particularly been found desirable toprovide the soles and heels of silk stockings with an exteriorlyinvisible interknitted lining thread, so to reinforce these parts, whilethe instep and the leg of the stocking is made of but a single thread.

My invention comprises novel and effective means for performing theplating operation and consists of the various features of constructionmore fully pointed in the appended claims.

In thc accompanying drawings: Figures 1, 2 and 3 are consecutive 'plansof the thread carrier sustaining bars' and coperating parts of myimproved straight knitting machine; Figs. 4, and (l are front elevationsof Figs. l, 2 and 3 respectively; Fig. 7 isn' sectional side view of oneof the guides for the shogging bars' and the left tappet rod; Fig. 8 asectional side vlewof one ot the guides t'or the shogging bars and theright tappet rod; Fig. S) an enlarged front View ot' one o't' thetappets; Fig. 10 a vertical cross section on line 10-10, Fig. 9; Fig. l1a cross section on line 11--1i, Fig. el, showing the thread carriers;Fig. 1Q a sectional end view of one ot' thc friction boxes; Fig. 13 asectional end view o'l one of the lixed stops and cooperating parts;Fig. 14 a front view of the stop; Fig. 15 illustrates the foot portionof an unlinished stocking knitted on the machine. and Fig. 1G shows astocking length haring plated high heels.

The drawings illustrate only those vparts of a straight knitting machineot the "lott0n type, which are pertinent to my invention, the partsomitted being of well known construction.

Throughout the length ot' the machine, extend a suitable number ofpreferably staggering shogging bars of which bars 20, 21,

22 only are used for carrying out my invention, while the additionalbars shown in Figs. 7, 8 and 13 arc used for purposes foreign to thisinvention, liars Q0, 2l, are slidably supported by suitable spacedguides 23 forming part o t' the machine frame. Bar f2.0 is the mainshogging bar and supports a plurality ot' main thread carriers Q4, whilebara 21, 2L are auxiliary shogging bars and support. respectively a likenumber of au'xiliary thread carriers 25, 2G. Carriers 24 are adapted totravel across the entire width of the stocking or other fabric to bemade and produce in conjunction with needles, sinkcrs and other wellknown elements of construction the meshes or loops 27 of the fabric.Carriers 25 are designed for lining or reinforcing the left` hand soleand heel portion Q8 oi: the stocking, while carriers 26 reinforce theright hand portion 29 thereof. After the tcet have been knitted down toinc 30 (Fig. '15), one set of auxiliary thread carriers is renderedinoperative, while the other auxiliary carriers travel across thc entirewidth of toe 31.

The movements ot' the main thread carriers and auxiliary thread carriersare so timed that the latter will lag for a uniform distance behind theformer, thereby insur` ing a true plating as more fully brought out inPatent #878,724 granted to me February 11th, 1908.

Reciprocativc movement is imparted lto `bars 20, 9.1, Q2 by means of ashifter bar 32 mounted in standards :lil and axially reciln'ocated bywell known mechanism (not. shown). Upon bar 32 is mounted a frictiondevice or box 3-1- `which when unchecked participates in the movement ofbar 3Q by lrictional contact. Upon a longitudinal spindlc 35 ot' box 34is mounted an arm 36 which is adapted to engage the corresponding rec 37of a lug 3S secured to bar Qt). The stroke o the latter is limited b v apair of adjusting screwst) tapped into the usual left and rightfashioning heads 4() ot the knitting machine.

Bar 21V receives reciprocative movement from shifter bar 32 by means ot'a parallel intermediary'tappet rod -ll arranged vertically above thelett hand portion ot' bar 2l and guided in hook-shaped keepers 4Q ofguides 23. To rod 41 is secured, by screws 43 an L-shapcd tappct 44 thedepending leg of which is received within a corresponding recess 45 of alug 46 secured to bar 2l by multaneousl vibrating the entire machineframe in a ongitudinal direction. It is obvious that with 'prolonged useof the Inachine, the shogging bar guides wear out, so that the barscarrying the thread guides are more apt to become slightly rocked orjammed, especially if there is provided the usual close fit between saidbars and the elements transmitting movement from the main shifter bar tothe thread guide bars. By interposing between said bars my novel tappetrods, the transmission of any rocking impulses from the shifter bar tothe thread guide bars is prevented, while owing to the slight playbetween the tappets and the recessed lugs of said thread guide bars theundesirable effect of rebounds is minimized.

I claim:

1. In a machine of the character described, a main shogging bar, a pairof auxiliary shogging bars, tappet rods operatively connected to theauxiliary shogging bars with freedom of movement relatively thereto, andmeans for reciprocating the main shogging bar and the tappet rods.

24. In a machine of the character described, a main shogging bar, anauxiliary shogging bar, a rod arranged in parallelism with said 'bai-s,a tappet on said rod, means for connecting the tappet to the auxiliaryshogging bar with freedom of movement relatively thereto, means forconnecting the rod to the main shogging bar, and means for reciprocatingthe main shogging bar.

3. In a machine of the characterdescribed, a main shogging bar, anauxiliary shogging bar, a recessed lug on the auxiliary shog ging bar, arod, a tappet on said rod that is loosely received within thelllg1'ecess, means for cfmnecting the main shogging bar to the rod, andmeans for reciprmfating said main shogging bar.

4. In a machine of the character described, a shogging bar, a recessedlug secured thereto, a. rod extendingr in parallelism with said bar andlocated vertically thereabove, means for intermittently reciprocatingsaid bar, and a tappet on said rod that is loosely received within thelug-recess, said recess being slightly larger than the tappet so thatthe latter has a play within the former.

5. In a machine of the character described, a shogging bar, a rodarranged in parallelism therewith, means for connecting the rod to thebar, said means permitting freedom of movement between said rod and bar,a pair of abutments on the rod, and a pair of reciprocative membersadapted to engage the abutments.

6. In a machine of the character described, a shogging bar, a rodarranged above said bar, means for connecting the rod to the bar, saidmeans permittingr freedom of movement between said rod and bar, a pairof abutments on the rod, a pair of reciprocative members adapted toengage the abutments, and stops for said members.

7.l Ina machine of the character described, a fashioning head, a stopcarried thereby, a shogging bar adapted to engage said stop, anadjusting screw carried b the shogging bar, a removable stop adapter tobe engaged by said screw, a tappet rod extending along part of theshogging bar, means for connecting said rod to said bar, with freedom ofmovement relatively thereto, and means for intermittent-ly reciprocatingthe tappet rod.

8. In a machine ot' the character described, a shogging bar, stopstherefor, a rod extending along part of said bar, 4a tappet on said rod,a recessed lng on the shogging bar engaged by the tappet, abutments onsaid rod, arms adapted to engage the abntments, friction devicescarrying said arms, 'and' stops for said devices.
